14-year-old Danny O'Neil (Gabriel Olds) is madly in love with his teacher, Miss Peggy Noble (Daphne Ashbrook). Given the fact that she is engaged to the cold-tempered and vicious gym teacher, Roy Kelton (Rick Rossovich), who is nicknamed Jackjaw for his constant threat of breaking his pupils' jaws, Danny goes through his school days somewhat uninspired and suffers in silence.
